A) By definition, you have that the period of the y=aCos(bx) is:
Period=2π/|b|
b=2π/3
Period=2π/(2π/3)
Period=3
b) The amplitude of y=aCos(bx) is:
Amplitude=|a|
Amplitude=1/4
c) The mideline represents the horintal line that passes between the maximum and minimum points. In the equation y=aCos(bx) the mideline is: y=0
Third table represents a linear function.
I think it’s b because linear functions usually have a straight line
So what I did was divide 214 by 2.2 and got 97kg
<u>Answer:</u>
42%
<u>Step-by-step explanation:</u>
We know that the number of times red side is faced up = 21; and
the total number of times colored chip is thrown = 50
Frequency of red side = (No of times red side is faced up / Total number of times colored chip is thrown) * 100%
Frequency of red side = (21 / 50) * 100% = 0.42 * 100 = 42%
Therefore, the relative frequency of the chip landing with the red side facing up is 42%.
